—The Evolved Packet Core (EPC), defined by 3GPP, provides the possibility of integrating 3GPP as well as non-3GPP access network technologies. This opens up new options for mobility through the use of inter system handover over several access network technologies. This paper provides an overview of the introduced component Access Network Discovery and(More)
BACKGROUND This study describes the transmission of border disease virus (BDV) from a persistently infected calf to seronegative heifers in early pregnancy, resulting in persistently infected fetuses. On day 50 of pregnancy (= day 0 of the infection phase), six heifers were co-housed in a free stall with a bull calf persistently infected with BDV (pi BVD)(More)
BACKGROUND Three Brown Swiss cows with abnormal regurgitation because of a perioesophageal disorder are described. CASE PRESENTATION The cows were ill and had poor appetite, salivation and regurgitation of poorly-chewed feed. Collection of rumen juice was successful in one cow, and in another, the tube could be advanced to the level of the 7th intercostal(More)
The Evolved Packet Core (EPC), IPbased, as defined by 3GPP, is the core network for the 4th generation networks. Within the EPC there are two mobility protocols defined to use on the S5/S8 interface between the Serving Gateway (SGW) and the Packet Data Network Gateway (PGW). The architecture and func-tionalities of the two involved gateways are different(More)
